(Variant for commodity_trading domain)
## Pattern
When two records have very similar names but different key identifiers
(model numbers, version numbers, specification codes), they should be
treated as distinct entities.
## Application to Insurance
- Policy with same holder but different coverage dates → different policies
- Same risk type but different deductible → different coverage terms
- Same broker with different registration numbers → different legal entities
## Exceptions
- Formatting differences only (hyphens, spaces, abbreviations) → same entity
- System-specific prefixes → same entity with different representation
- Historical name changes due to rebranding → same entity
## Decision Framework
1. Strip formatting differences
2. Compare key identifiers (not just name)
3. If identifiers match → same entity
4. If identifiers differ → distinct entities
5. If ambiguous → escalate to domain expert
